SpecificationfoflLettersPatentl To all tvhom "it may concern: 1 I Be it known that I, ROY T. AXE, of Syracuse, in the county of Onondaga and State.

of New York, a citizen of the United States, have invented a certain new, and useful lVinding-Roller, of whichthe following is a specification. g

- This inventionrelates to winding or spring" rollers for windows, window shades andthe like, and has for its object means for supporting the fixed axleoftheroller; and the invention consists in the o'ombinationsand constructions hereinafter set forth and claimed.

In describing this invention referenceis had to the accompanying drawing in which designate corresponding parts in all the views. a I I a Figure 1 is a longitudinal sectional view, partly broken away, ofya roller embodying my: invention. Fig.2 is a faceview of one of the discoidal sheet metal heads. is an end'view of the axle. 1

1 is the body of the roller, the same being a sheet metal shell rolled cylindrical in form.

2 and 3 are the members of a pair of heads located within one end portion of the shell, the heads being here shown as located some distance from one end of the shell, and 4 is an additional .head located at the. extreme end of the shell. a I Each of the heads 2, 3;.are sheet metal disks having central offset bosses5. projecting toward and preferably engaging each other, the flange portions of the disks 2, 3 being spaced apart. The bosses '5 are here shown as spherical and as engaging. each.

other at their centers and provided with openings as 6 at theircenters.

The head 1 located at theextreme end of the shell 1 is also a sheet metal disk formed with a central offset boss 7 similar to the bosses 5, and provided with a central opening, the boss 7 projecting outwardly.

i 8 is an axle ortrunnion supported by the heads 2, 3, 41, the axle extending through the openings 6 of the heads 2, 3 and the opening of the head 4 and the. portion thereof between the heads 3 and 4E being'provided with integral peripheral shoulders 9'for engaging opposing faces of the bossesof the disks 3, 4.

The head 2 abuts against an internal circuniferential shoulder 10 with which the shell lis provided, and the head 4 is held in position by the inturned margin l1v at one 'Fig. 3 g end to said axle sections and at its other end 'end of the shell 1, said 11' J engaging the outer face :ofrthe'disk t. Hence the j dlsks are 'held from axialmovement by the shoulder 10 and inturned margin 11, and the disk 3 is'fheld spaced apart from the disk'2 p PatentedDec.17,1912. Application filed my 2, 1912. Serial No. 107,157.

by reason of the fact that the bosses 5 are engaged. with eachother, and the disks are shoulders Blot-the axle 8. p The described construction support is particularly advantageous in that the axle and the disks supporting the same are rigidlyheld in positionin the shell-1, and owing to the fact that the bosses 5 of the disks 2, 3 engage each other, a maximum rigidity. of the disks 2, 3 is provided for.

of the axle held from inward movement toward each other or from inward displacement'bythe I 12 and13 are sections ofan axle journaled in ahead? 14;at on'eendof the shell and an anchor 15 located within the shell 1, the axle being acted upon by a spring 16 coiled about the axle'sections 12, 13 and connected at one to the anchor 12.

The construction and operation of the parts 12 to 16 inclusive form no part of this invention but form the subject matter of another application. What I claim is:

1. A winding roller comprising a hollow. metallic shell, a pair of-heads located within the shell and having ofi'set bosses projecting toward each other and having central openings, and an axle extending-into said openings, substantially as and for the purpose described. I a

2. A winding roller comprising a hollow metallic shell, a pair of heads locatedin one end portion of the shell andhavingcentral offset bosses projecting toward andengaging each other, the flange portions of the heads being spaced apart, and the bosses being formed with axial openings, and an axle extending into said openings. substantially as and for the purpose specified. I

3. A winding roller comprising a hollow metallic shell, a pair of heads located in one end portion of the shell, and a head located at the extreme end of the shell andhaving a central opening, the pairof heads being formed with central oflse't'bosses projecting toward each other, and the bosses having central openings,- and an axle extending through the openings of the heads and having peripheral shoulders engaging the opmetallic shell formed with an toward and engaging each other, the flange portions of the heads being spaced apart and one of said heads engaging said shoulder, a discoidal sheet metal head located at the extremeend of the shell, the margin at one end of the shell being turned inwardly onto "the outer face of the last-mentioned head, an axle supported by the heads and having peripheral shoulders engaging opposing faces of the outer head and of one of said 2 pair of heads, substantially as and for the purpose described.

5. A winding roller comprising a'metallic shell formed with an internal shoulder spaced apart from one end thereof, a pair of discoidal sheet metal heads located within the shell, the heads being formed with central offset bosses projecting toward and engaging each other, the bosses having central openings, the flange portions of the heads being spaced apart and one of said heads engaging said shoulder, a discoidal sheet metal head located at the extreme end of the shell, and having a central offset boss formed with a central opening, and an aXle extending through the openings of the bosses of the heads and having peripheral shoulders engaging opposing faces of the bosses of the outer head and one of the inner heads, aubstantially as and for the purpose speci- 6; A winding roller comprising a metallic shell, heads located in one end portion of the shell and spaced apart, the heads having central offset bosses substantially spherical, the bosses projecting toward and engaging each other and being formed with cen tral openings, and an axle extending into said openings, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 27th day of June 1912.
